Disgusting? Sure, but not to de Blasio. He says Rivera broke no laws (owning another apartment somehow didn’t disqualify the couple for Section 8 housing) — so therefore she has acted “appropriately.”

And never mind that the couple is depriving a more needy family of an affordable apartment — at taxpayers’ expense.

It’s all so familiar. After all, de Blasio himself deems his own pay-to-play behavior for the past four years “appropriate,” even though they triggered a raft of probes. His reasoning? He was never officially charged with a crime.

That is, it’s OK to do special favors for fat-cat donors, so long as you’re not caught.

Yet in not seeking charges, Manhattan DA Cy Vance Jr. made it clear that Team de Blasio violated the “spirit” of campaign-finance laws. Hizzoner’s fundraising for state Senate candidates, said Vance, was “intended to evade campaign-finance limits.”

De Blasio insists he acted “appropriately,” because he got away with his actions. It’s a repugnant way to conduct city business.

Legal or not, New Yorkers should be outraged by both Rivera’s and de Blasio’s shenanigans. Lucky for voters, they’ll have an opportunity to voice that outrage in just two months — on Election Day.
